How to write a prompt that actually works

The difference between a mediocre AI output and a great one is almost always the prompt, not the model. Here are the four elements that make any prompt work reliably.

1 — Role

Tell the AI who to be. "Act as a senior copywriter with B2B SaaS experience" produces different output than a blank prompt. The role anchors tone, vocabulary, and depth.

2 — Task

Be specific about what you want. "Write an email" is too vague. "Write a 150-word cold outreach email to a CFO offering a cost audit" is specific enough to get a usable first draft.

3 — Format

Tell it exactly how to structure the output. "Give me 5 bullet points", "Write in markdown", "Use headers for each section", "Under 200 words". Format constraints prevent bloated, unusable responses.

4 — Constraints

What NOT to do is often more valuable than what to do. "No buzzwords", "Don't use passive voice", "Don't recommend paid tools" — constraints save you editing time and keep the output inside your guardrails.

Prompting tips by tool

Claude — Responds best to long, detailed prompts with clear structure. Give it context freely. Use numbered lists for complex instructions. Say "think step by step" for analytical tasks.
ChatGPT — Works well with conversational prompts and follow-ups. Use the system prompt (custom instructions) to set your persona once instead of repeating it in every message.
Midjourney — Style words matter more than sentences. Lead with subject, then style, then technical parameters (--ar, --v, --style). Use /describe on an image you like to reverse-engineer good prompts.
Perplexity — Ask for sources explicitly and set a date range. It's a research tool, not a writing tool — use it to find information, then take that to Claude or ChatGPT to synthesise and write.
